文章运用中国高龄老人健康长寿追踪研究1998-2002年的数据,将自评健康作为随时间变化的变量,对年龄范围在80-105岁的高龄老人考察自评健康与死亡风险的关系。研究结果表明,在控制基期社会人口特征、日常活动的参与程度、生理功能以及患慢性病数量后,自评健康显著预测高龄老人的死亡风险。日常活动的参与程度和生理功能只解释了它部分的预测作用。进一步的分性别分析表明,自评健康与死亡风险的关系在性别间差异非常小。
Using the 1998-2002 data from the Health and Longevity Tracker for the Elderly in China, the article uses self-rated health as a variable over time to examine the relationship between health and mortality risk for elderly people aged 80-105 years old. The results of the study indicate that self-rated health significantly predicts the risk of dying in the elderly with control over the demographic characteristics of the population, the level of participation in daily activities, physical functioning and the number of chronic diseases in the baseline period. Daily activity participation and physiological function only explain its part of the predictive role. A further gender-segregation analysis shows that the relationship between self-rated health and the risk of death is very small among the sexes.
